ITRF

The International Terrestrial Reference Frame (ITRF) is a highly precise, global coordinate system that maps Earth's surface and shape. It provides a consistent framework for pinpointing locations on Earth by measuring positions of locations, satellites, and other objects with great accuracy. This system accounts for Earth's moving plates, shape changes, and crustal shifts over time, ensuring reliable positioning data for scientific research, navigation, and Earth monitoring. Essentially, ITRF acts as a universal reference point, allowing accurate, consistent location measurement worldwide.
